ResumoThe mechanism of isomerization of methyloxirane to propanal and acetone was studied on a Cu catalyst. During the transformation, the deoxidation reaction causes the oxidation of the catalyst surface, and Lewis acid site-basic site pairs are produced. Propanal is formed predominantly on these centers. The rate of formation of such active centers, and hence that of propanal, is maximum on the partially oxidized surface. Acetone is formed on the reduced metal surface. Both reactions may be regarded as hydroisomerization.
